This is a must have cd single for fans of GG's first release in 1972 as it includes the long version of RnR.This is on my cd player at 5:06 - the instrumental starts and the lyrics kick in at 2:59. It's a good version with the tribal rhythms building up nicely.The two other tracks (the original A & B sides) are both 2:59 on my player.They seem to be from the original masters, I know complaints have been made that compilations of Glitter have tampered with mixes.This is a nice one for the collection, has a clean, crisp sound and is up there with the Glam Years compilation.Cd is in a full size jewel case and is over 11 minutes in full length.Definitely a classic single and a true stone cold glam rock mega stomper.Highly recommended.
